SPECIFICATION formingpart of Letters Patent- No. 228,538, dated June 8, 1880.

Application tiled April 27, 1880.

(No model.)

To all 'whom t may concern:

Beit known that I, GEORGE Knirrz, a citizen of the United States, residing at Evansville, in the county of Vanderburg` and State of Indiana, have invented certain new and useful Improvements in Pumps and Feed-7ater Heaters for Steam-Engines, and l do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a longitudinal section of my invention, and Fig. 2 is a side elevation, partly in section.

The present invention has relation to certain new and useful improvements in pumps and feed-water heaters for steam-engines, and the object thereof is to provide a cheap, durable, and simple pump to be attached to a portable or semi-portable engine for washin g out sediment that accumulates in the boiler.

A further object is to construct the pump in such a manner that it cannot be lost, damaged, or neglected, as is the case with the pumps independent of the engines, and also to attach it to the same pump-valves and pump used to keep up the supply of water in the boiler while the engine is in operation, and for purpose of extinguishing fire, washing the engine, and for such other purposes as a pump is generally used for about an engine.

A further object of the invention is to provide means for heating the water in the tank or barrel previous to its being forced into the boiler.'

The invention consists in the details of construction as represented in the drawings and hereinafter described, also pointed out in the claims.

In the accompanying drawings, A represents the cylinder ot' a force-pump commonly attached to an engine for keeping up the supply of water in the boiler. The pump-cylinder A may be either vertical or horizontal, as circumstances may require, and is provided with a plunger, a, passing through a stuffing-box, l), said plunger being driven by the engine. The cylinder A is connected with a valvechamber, B, by coupling-section c.

The cylinder Aand section c are provided with plugs d, which may be removed for placing the hand-pump, hereinafter described, into different positions to suit thc will of the operator. The valve-chamber B has a suitable airchamber, C, connected thereto -in any suitable manner that will admit of its being removed when it is desired to remove the valves cj', said valves resting` on valve-seats g, formed in the chamber. Y A

rlhe hand-pump consists of the cylinder D, which also communicates with the valve-charnber B by coupling-section 7L. The cylinder D is provided at its lower end with a valve, i, so that when the hand-pump is not used communication between it and the valve-chamber B is closed. The cylinder D has a piston, 7c, of any suitable construction for operating the pump, said piston passing 'through a stuflingbok at the upper end of the cylinder.

The valve-chamber B has an opening, l, into which suction-hose is attached by any convenient means.

The heater (represented at E) has suit-able heads m, with inlet and outlet openings to admit the escape-steam of eugires to pass through, said cylinder containing v'coils or pipes n o, through which the feed-water is forced. The pipes a o pass through the side of the heater E, near the upper end thereof, the pipe What-*ing a valve, p, to which the return-hose is attached7 and an opening in the sleeve q, for attaching the supply-pipe, which leads the supply of "water through the checkvalve and boiler. The pipe o connects with the chamber B and has a removable plug, r, so that in case cold water is required to be returned to the tank the plug may be removed and the valve p screwed on with the returnhose without altering or affecting the working of the hand-pump for washing and other purposes.

The operation of the pump is as follows, it being understood that it is arranged to work constantly, whether pumping into boiler or not: WVhen the water is not passing into boiler it must of course be returned to the tank or barrel, and for this purpose the return-hose hereinbeforc mentioned is employed in connection with the valve attached to supply-pipe at any IOO convenient place between check-valve on boiler and injecting-pipe on heater-coil, no stop-cock to gage the watersupply in suction -hose being used, but allowing' the pump to work up to its full capacity all the time. The supply of water is gaged by the valve p, which connects supply-pipe with return-hose. By properly adjusting the valve p a steady stream is supplied to boiler, the required amount passing through the valve-openings in the chamber B, the remainder returning through valve p and the hose to the tank or barrel. The water returned to the tank or barrel passes through heated coils, and consequently is heated to a high degree as it passes in its course to said tank or barrel.

I am aware that suction and return hose have previously been used by connecting them to the supl'lly-pipe between pump and heater, which would return cold water through hose and pipe connections to barrel or tank.

In case thel boiler requires cleaning, the hose (both suction and discharge) which is com monly used on portable and semi-portable engines is brought into use by closing the supply oi' from the boiler by shutting' ott the valve. The return hose valve p is opened, which allows the water to pass through the hose. Valve 'i on the lower part of hand-pump D is opened, which allows hand-pum p to work freely for washing or other purposes.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In combination with a portable or steam lire engine, an auxiliary pump, A, connected to the boiler and having an overow and valve, 7,), constructed and arranged substantially as shown, and for the purpose set forth.

2. In combination with a portable or steam fire engine, an auxiliary pump, A, connected to the boiler by means of a feed-water heater, E, and provided with an overflow and valve, 1J, constructed and arranged substantially as shown and described. v

3. In a portable or steam fire engine, an auxi liary pump, A, provided with valve-chamber- B, and connected to a feed-water heater, E, having coils or pipes n o, and hand-pump l), all constructed and arranged substantially as shown and described.

4. In a portable or steam fire engine, the combination of the pump A, having valve chamber B, with the heater E and hand-pump D, provided with stop-valve t', substantially as shown and described.

5. In a portable or steam fire engine, the combination ot' an auxiliary pump, A, having valve-chamber B, connected to hand-pump D, provided with stop-valve t', and the heater E, having coils or pipes n o, substantially as and for the purpose set forth.

6. In a portable or steam fire engine, the combination of an auxiliary pump, A, having valve chamber B, Water heater E, provided with coils or pipes n o, and a connection, d, for attachment of a hose, all constructed and arranged substantially as and for the purpose specitied.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

GEORGE KRATZ.
